MINING APPARATUS.

Application filed .Tune 13, 1919, Serial No. 304,069. Renewed November 25, 1927.

My invention relates to mining apparatus.

It has for its object to provide an improved mining apparatus especially adapted to room or entry work and having increased fieXibility, whereby the same may be readily trans ported and when desired adapted to service under varying conditions. A further object of my invention is to provide an improved truck mounted kerf cutting apparatus having improved supporting, guiding and adjusting means, preferably normally forming a part of a compact truck mounted structure and adapted, while still supported by the truck, to insert a transverse kerf in a face across the front of the truck between points disposed laterally substantially beyond the lines of the truck. Further objects of my invention include the provision of improved means whereby the apparatus may be utilized to cut room necks or cross. cuts or a kerf in an oblique face, or rooms or entries of varying width. These and other objects and advantages of my improved construction will, however. hereinafter more fully appear.

In the accompanying drawings I have shown for purposes of illustration one embodiment whichmy invention may assum in aracticc.

11 these drawings,

Fig. 8 a diagrammatic view showing the apparatus use on a diagonal face.

In this illustrative construction, I have shown a machine of the general construction described and claimed in my co-pending application Serial No. 260,708, over which this application covers an improved adaptation. As the construction of the machine per se is described and claimed in that application and does not enter specifically into this invention, it will therefore here suflice to say that a machine frame 1 is provided having thereon a rotatable element 2 and a rotatable element 3, adjustable one relative to the other, so that a cutter bar 4 carried by an enlarged front head 5. and itself carrying the usual cutter chain 6, may be adjusted into any desired plane relative to the face, and thereafter swung transversely in the desired plane through suitable power operated mechanism (not shown) carried within the front head 5 and controlled by suitable controlling means including a member 7.

In my improved construction it will be observed that the rear end of the frame 1 is provided with a feed driving member 8 driven from the machine in a usual manner and rotatable on a'vertical axis, herein. in the form of a usual chain driving sprocket. and provided with suitable cooperating guiding members 9 disposed on the front and rear ends of-the frame and adapted to oooperate with a feed chain 10 in a well known manner. As shown, the frame 1 is disposed horizontally in and fixed to a swiveled frame 11, which is in turn swiveled at 12 and slidably supported in an elongated longitudi nally disposed guiding frame 13. As shown, this frame is itself also slidably mounted in a lower, herein shorter, frame 14, in turn swiveled at 15 on the wheeled truck frame 16 and with the swivel 15 slidable longitudinally of the latter frame. Thus it will be observed that a construction is provided which may be compactly assembled for transport in the normal longitudinally disposed transport position of the parts illustrated in Figs. 1 and 2 and which may be conveniently transported from place to place about the mine in a usual manner as by providing a suitable mot-or drive for the truck. Hereim for con.- venience this truck drive is illustrated, in the form of a separate truck driving motor 17 carried on the rear end of the frame 16 and operatively connected to the truck wheels 18.

When. my improved apparatus with its ri rib, it will be observed that hi0 cutter bar parts in transport position is brought i to aroom, a suitable support, herein in the form of a plurality of jacks 19, is set beneath the front end of the truck frame 16. Through operatively connecting the chain 10 with one or the other of a plurality of hooks 20 on the opposite sides of the front end of the truck frame, it will be observed that the machine may then be fed forward with the frame 13 and frame 14 to of the truck frame 16 During this movement, it will also be observed that through operation of the controlling memher 7, the cutter bar a may be swung to the right or left, as shown in Figs. 3 or it. Afte this movement, the front end of the frame 13 is also preferably smingabout its swivel, manually or, if desired, by suitably connecting the chain 10 to one of a pair of hooks 31 on the front end of the fran'ie. In Fig. 3, wherein the out is to be stz-n'ted at the ght swung to the left and the front end of the frame 13 is swung to the hi until it 00- cupies the transverse pot on 1 heated. In

this position of the frame 13, the ri I Then, through coo-r of the feed chain 10 with one of 1 21, the machine is fed from the position shown in Fig. 3 to the position shown in Fig. 5, with its bar preferably still disposed transversely. As soon the machine frame is disposed in the posi Ion shown at the right in Fig. 5, i. e. cl sely ad acent the ight rib, through manipulation of the controlling member 7 the bar 1 is swung to the right from the transverse position illustrated to sump it under the'coal, as also shown in Fig. 5. When the bar has thus been sumped in under the coal, it will be observed that by again simply connecting the chain 10 one of a plurality of hooks 23 provided at the opposite end of the frame 13 and, .if necessary, placing suitable jacks Q- lin position at that end of the frame, the machine may be started toward the left upon its t'ansverse cut. When the machine, however, reaches a jacks 22.

position over the front end of the truck frame 16, the movement of the same is stopped and the jacks 22 and 23 at the opposite ends of the frame 13 are removed. Then, after a suit-able jack is placed against the machine, as shown in Fig. 6, the feed chain 10 is connected to the books 21 on the right hand end of the f nine 13 so that by the pull of the chain the frame 13 may be slid beneath the machine frame transversely from the position shown in full lines in Fig. 6 to the position shown in dotted lines in that figure. Obviously, upon then removing,- the jack 9.5 and suitably setting the supporting jacks 22 and operating the mechanism as heretofore, the transverse cut be completed by running the machine over into engagement with a position on the front end the left rib. Then the bar may be removed from the cut and the mechanism assembled in transport position on the truck ready for transport to another place. in Fig. 4 it will be observed that I have illustrated an intermediate step in the disposition of the machine for starting a cut at the left hand rib. In this use of the apparatus, it will be observed that the machine is moved forward as in F lg. 3, but that, on the contrary, the bar at is swung to the right and the frame 13 is swung to the left. Obviously, with the parts in this position, through the connection of the mechanism as hereinabove described, the machine may be supported and moved laterally into sumping position at the left hand rib, sumped in under the coal, and then moved to the right to make a transverse out toward the right rib with substantially the same ope 'ation in the same stages as described above in connection with the disclosures in Figs. 3, 5, and 6.

In Fig. 7 I have also illustrated the use of my improved apparatus in cutting room necks or cross cuts. In this use of the same it will be observed that the frame 13 is simply swung about its swivel in such a manner as to bring the machine opposite the center line of the ClOSliQCl room neck or cross cut, the end of ,chine is moved bodily forward in such m anner as to cause its bar to occupy the dotted line position A. From this position, th rough further operation of the controlling member 7, the bar is then swung laterally into the dotted line position The withdrawal cut, which results in the bar being; brought to the dotted line position C, is then made by simply connecting the end of the feed chai :1 10 to one of the hooks 23 at the rear end of the frame 13, the rear end of the latter at that time preferably being fixed in position by the jacks 2 1 In Fig. 31 have also illustrated my improved mechanism as applied to use in cut ting; an oblique face. A cut this type desired under certain service eon litions and is readily obtained in my innarovcd construction wherein the-frame 13 may obviously be readily swiveled into parallelism with any desired face, and the may beadjusted angularly relative to the frame, the ribs being kept straight by varying the angle of the bar. Here it will also be observed that since improved construction is capable of being so disposed angularly, it is thereby adapted to use in rooms or entries of varying width, the

angle of the out being varied as desired to accommodate the mechanism to any particular width. 7

In the use of my improvement, it will be observed that the machine is stably supperte and guided during a cut, either transversely in advance of the truck or at the side thereof, and when the machine is disposed at a point laterally beyond the trucL, thereby giving a greater range of guided moven'ient. It will also be observed that the supporting mechanism provided, while thus adapted to support the machine, is also capable of being very compactly disposed during transport, 1'. within the lines of the truck. I-Iere, attention is also directed to the fact that through the use of guiding and supporting frames 13 of varying length, the apparatus may be adapted to out either rooms or entries, as desired, and that with a frame of a given width the width of the entry or room cut may be va l as desired by varying the angle of the ii- 13 relative to a transv line. These a other advantages of my improved construction will, however, be clearly apparent to those skilled in the art.

IVhile I have in this application specifically described one embodiment whr my invention may assume in practice, it stood that this form is used forillustrative purposes and that the invention may be modified and embodied in various other forms without departing from its spirit or the scope of the appended claims.
